I'm on Ecma TC39 and I care a lot about Node. We've explicitly approached
modules with both the browser and Node in mind.

Yes. I've been pushing since New Years for ES6 not to require any kind of
opt-in at all, and to be backwards-compatible with ES5:
https://mail.mozilla.org/pipermail/es-discuss/2011-December/019112.html
Part of that means that any existing code that uses `module` as an identifier
will continue to work as before. I believe this approach has come pretty close
to consensus on TC39.

That's right.

Both directions should be possible. ES6 modules will be usable as modules out
of the box; for using objects as modules, the loaders API allows for installing
ordinary objects as modules. This has to be done before loading code that
statically requires it, but this could possibly be done automatically by Node
at startup. Finally, the ES6 API for dynamic loading is async, but there's
nothing preventing Node from adding an extra synchronous API for loading
modules, à la require().
